2015 Infiniti Q50 2.1L Diesel · RX65 ZTH

The vehicle currently holds a valid MOT certificate following the October 2025 test at 119,344 miles, yet the maintenance trajectory reveals a pattern of deferred mechanical attention rather than proactive upkeep. The most recent examination cleared the car only after the operator corrected a parking brake efficiency failure recorded earlier that same day. Brake performance has consistently struggled across the last two annual inspections. The October 2024 test flagged imbalanced rear brakes and excessive travel in the parking brake lever, while the 2025 failure cited parking brake efficiency below requirements. This recurring deficiency indicates the braking system receives only reactive servicing when mandated by test failure. Tyre wear now mirrors this neglect, with both nearside front and rear rubber flagged as worn close to the legal limit and exhibiting edge wear during the final October 2025 assessment. The recorded mileage progression aligns closely with typical usage for an eleven-year-old executive saloon, averaging approximately 10,850 miles annually. The vehicle covered roughly 11,700 miles between the October 2023 test at 97,166 miles and the October 2024 examination at 107,639 miles. A further 11,700 miles accumulated before the October 2025 assessment at 119,344 miles. This steady accumulation suggests consistent daily commuting rather than sporadic short trips or prolonged storage. The uniform annual mileage increase places predictable stress on wear items, which makes the delayed replacement of suspension linkages and brake components more concerning. The data shows no unexplained gaps or sudden mileage spikes, confirming the odometer reading reflects genuine road use. A prospective purchaser must verify the condition of the front suspension and secondary safety mechanisms before committing to the purchase. The October 2024 failure documented an excessively worn nearside front anti-roll bar linkage ball joint, while the preceding October 2023 advisory noted slight play in both front lower suspension arm ball joints. This progression from slight play to excessive wear demonstrates a clear deterioration in the front axle geometry that likely compromises handling precision. The seized secondary bonnet latch recorded in October 2024 also warrants physical inspection to confirm the primary catch operates without binding. The persistent windscreen damage advisories across three consecutive tests indicate the previous owner tolerated cosmetic degradation rather than addressing it promptly. Buyers should commission an independent brake dynamometer test to confirm the parking brake and rear braking balance now operate within specification, and inspect the nearside tyres for structural damage caused by the reported edge wear.
